Hey Harry, I just posted a video of making your welded holdfasts "they work GREAT by the way". I had some notes from 2008 that I worked from and I know you posted them but I can't find the thread or pictures on this site to give a link in my video description. If you happen to know where it is, let me know and I'll add it to the description. if your interested here is the video: https://youtu.be/Et_yISw0OA8
